I have created a search category function. which work fine

after that When i click Edit button it goes to first row of the gridview to edit the row

or if i click 2nd row from the search data i goes to 2nd row from gridview in edit mode.

Please help me.. i am not able to find the cause of this problem
if (e.CommandName == "EditRow")
                int rowIndex = ((GridViewRow)((LinkButton)e.CommandSource).NamingContainer).RowIndex;
                gvMainCategory.EditIndex = rowIndex;
//DataBinding method
        private void bindMC()
            int counter = 1;
            counter = counter + 1;

            BL_MainCategory objBL_getMC = new BL_MainCategory();
            gvMainCategory.DataSource = objBL_getMC.LoadCategory();
private DataSet ExecuteSelectSQL(string sqlcmd)
            string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(CS))
                SqlDataAdapter da = new SqlDataAdapter(sqlcmd, con);
                DataSet ds = new DataSet();
                return ds;

        public DataSet LoadMainCategory()

            DataSet ds = new DataSet();
            string sql = "select * from MainCategory";
            ds = ExecuteSelectSQL(sql);
            return ds;

I try to debug the edit method after filtering.

I came to know that the gridveiw edit index is setting to -1.

i think this the problem
